Old habit, removed.

Done.

Will do, in testing i suppose.

BTW : The driver need lot of parameters to be passed from user-space calibration
tool. The best way to do it isn't decided yet : one sysfs file per parameter, or
one sysfs file for all, with a big sscanf parsing. Any idea ?

Something like this ? :

if (strlcat(ebeam->name, ")", sizeof(ebeam->name))>=sizeof(ebeam->name)) {
// overflowed, closing ) anyway
ebeam->name[sizeof(ebeam->name)-2] = ')';

Thanks.
